This invention relates to improvements,

in molds for plastic material.

An object of this invention is to provide a mold of novel constructiondesigned for forming blocks or any other construction of aself-hardening plastic material being of several that a type of-mosaicof difierent colors, so

material, the plastic different kinds or construction which iscompletely formed of self-hardening plastic made."

Another obj materials can be ect ofthis invention is to provide a moldconsisting essentially of a supporting pallet having side walls andhaving partitions adapted to be positioned on the supporting pallet todivide the space between the side walls into various compartments intowhich difierent self-hardening plastic materials may 7 a novelconstruction wherem there provide be placed, and to is. a joint betweenthe pallet and the partitions which will prevent the escape of oneplastic material from one compartment into another, which might causeundesirable mixing.

A. further object 01' provide a mold having about which side walls thisinvention is to,

a supporting pallet are arranged and which has its'interior divided intocompartments, and to provide the supporting pallet with a removableporti which is hereinafter to With the foregoing and on,- the purpose ofbe described. 7

other objects in View which will be made manifest in the followingdetailed description and specifically pointed out in the'appendedclaims, reterenc'e is had to the'acco mpanying drawings for anillustrative embodiment of the invention, wherein F igurel is aperspective view of thesupporting pallet with the partitions appliedthereto,

"Fig.2 is a vertical se tially on the line 22 trating the side walls ofto the pallet, and n Fig. 3 is a perspec showingthe mold in invertedposition after 7 plastic materials have been placed therethe ction takensubstanof Fig. 1 and illusthe mold as applied tive sectional view in andillustrating the utility of having a portion of the pallet removable.

Referring to the accompanying drawings wherein similar referencecharacters designate similar parts throu which may be of any ghout, theimproved mold consists of a supporting pallet 10 desired shape and whichis illustrated as being rectangular in form. Sides 11 are'provided forthe'pallet, such sides being so'arranged as to conform withithe edgesofthe supporting pallet and may be provided'by the conventional flask becaused to form anyother design which I be desired. 7 Centrally of thebeads or ridges and on top thereof there are formed grooves 13 whichpreferably have a very slight taper from their tops downwardly.Partitions 14 are provided which are preferably formed or sheet metaland which correspond to the beadsiorridges 12. These partitions areadapted to bepositioned on the beads-and have their lower edges fittingwithin-the grooves 13. The center.portion of the pallet, indicated at15, is shown as being removable ,with its edge portions abutting theoverhanging parts of the inside beads or half rounds'12. n

In' use the mold is assembled, as shown in Fig. 2, wherein the variouspartitions 14 serve to divide the space between the side walls 11intocompartments. Each compartment is adapted to receive a selt'hardening plastic material, and the various self-hardening materialswhich areplaced in the different compartments may be of dilierentcolors. For example, .a. blue material can be placed in the outercompartment 16, a

white -material can be placed in the inter- .mediate compartment 17 anda red material can be placed in the central compartment 18;. Thepartitions serve to keep these materials from mixing with one another,and

asltheir lower edges fit within the grooves on-the beads 12, akjoint isthus provided filled, iorming a clear'line of distinction betWeen onecolor and another. y

'shape of the compartments, partitions and beads may befvaried to cause;the covering on the face of the blockto assume; different designs fromthat shown; Furthermore, the

, number, of compartments can be readily increased or decreased, as'desired, and the colors of the materials placed therein can alsobevaried. V

It will be understood that various-changes may be made, in the detail ofconstruction Without departing from the spirit or scope of the inventionas defined by the" appended claims.
